| Abstract: |
| Objective To simulate and calculate the ships collided condition of floating nuclear reactor, calculate and compare the simplified models of pressurizers based on different treatment methods. Methods Based on simulating calculation on ships collided condition of floating nuclear reactor, the length, width and height directions acceleration of pressurizer supporting were obtained, and response spectrum treatment of time history was completed. Through the input loads of equivalent static analysis, spectrum analysis and time-history analysis by ANSYS, the support loads and top displacement of pressurizer were calculated, and the three kinds of results were compared. Results The axial force, shear force and bending moment of pressurizer support calculated by equivalent static analysis were 1.25?106 N, 6.97?105 N and 2.08?109 N?mm. The axial force, shear force and bending moment of pressurizer support calculated by spectrum analysis were 1.90?105 N, 2.63?105 N and 1.10?109 N?mm. The axial force, shear force and bending moment of pressurizer support calculated by time-history analysis were 2.03?105 N, 3.54?105 N and 1.15?109 N?mm. Conclusion It proves that the method of calculating ships collided condition is feasible in the paper. For different input loads dispose methods, the structure response is different. For analysis case in this paper, the static analysis results are larger than spectrum analysis results, and the spectrum analysis results are approximately equal to time-history analysis results. |
